Preferred embodiment describes in detail
At first referring to Fig. 1-4, Fig. 1-the 4th is according to the schematic representation of a valve assembly of the present invention.Valve assembly 12 comprises valve body 14, and this valve body 14 has liquid inlet 16 and liquid outlet 18.(as understandable, the term " outlet " relevant with this embodiment and the use of " inlet " are in fact just for convenience's sake.Here valve is symmetrical, and the effect of entrance and exit can reverse).Be placed in inlet 16 and export between 18 and what the two was separated is an elastic diaphragm 20, this for example silicone rubber manufacturing of barrier film 20 usefulness.As what in Fig. 2, seen, a hole 22 is arranged in barrier film 20, described barrier film 20 is in the position that does not have pressure reduction between the both sides of barrier film, and hole wall is collapsed and the hole Close All.
When by entering the mouth 16 when applying fluid pressure (schematically illustrating with arrow) in Fig. 3, barrier film 20 distortion also trail, so opening enlarges, and form the perforate that flow of liquid is crossed, as seeing among Fig. 4.
Referring now to Fig. 5,, Fig. 5 illustrates the valve assembly 30 according to one embodiment of the invention.Valve assembly comprises valve casing 32, and valve casing 32 is made up of two members that cooperatively interact 34 and 36.Member 34 defines a fluid input 38, and member 36 defines a fluid output 40, and exporting 40 in this case is road strategic point type (luer-type) connectors.Barrier film 42 is placed between the entrance and exit, and by member 34 and 36 and put partial fixing in position.
Barrier film 42 has a hole, and this hole is closed in position of rest shown in Figure 5.When applying fluid pressure, barrier film is distortion (dotting) just, and open so that fluid flows in hole 44.The same with the valve assembly situation of Fig. 1-4, liquid can flow along any direction in principle, this depends on the direction that applies fluid (be again for convenience's sake parts 38 and 40 to be defined as " inlet " and " outlet " respectively, though are preferred directions from 38 flow directions to outlet 40 that enter the mouth) here.
Referring now to Fig. 6,, Fig. 6 illustrates the valve assembly 50 according to another embodiment of the present invention, only allows liquid to flow along a direction in this valve assembly 50.Valve assembly 50 comprises a valve casing 52, and valve casing 52 is made up of first member 54 and second member 56, and they define inlet 58 and outlet 60 respectively, and this outlet 60 is road strategic point type connectors.Be placed in the valve casing 52 and be fixed on member 54 and 56 and to put between the part be an elastic diaphragm 62.Just as seen, member 54 has a wall section 64, it and barrier film 62 keeping parallelisms, thereby barrier film 62 can only be gone up distortion in the direction (towards the direction of outlet 60) opposite with this wall section 64.When the fluid pressure that applies from 58 (the representing with arrow) that entered the mouth surpasses a certain threshold value, barrier film is distortion (this deformable members dots) just, and upwards open in a hole that is pre-existing in the barrier film 66, allows fluid flow at inlet 58 with between exporting 60 then.
Referring now to Fig. 7 and Fig. 8,, Fig. 7 and Fig. 8 illustrate the valve assembly 70 according to another embodiment.This embodiment and difference embodiment illustrated in fig. 6 are first member 74, and in fact all other members identical with label among Fig. 6 carry out identical functions.Member 74 has a core 80, and this core 80 defines 82 and annular protrusions 84 of an inlet, and this annular protrusion 84 is positioned near barrier film 62 places.Core 80 is connected on the periphery 86 of member 74 by the flexible shoulder 88 of a centre, and this flexible shoulder 88 can be done motion to axial between core 82 and periphery 86.
Periphery moves so that when being pressed on the member 62 when the center part is being pasted, as what in Fig. 8, can see, flow of fluid is opened and made to barrier film just distortion and hole 66, and this embodiment's assembly is operated in the mode identical with configuration among Fig. 6 basically, that is it only allows unidirectional flow of fluid.
Referring now to Fig. 9,, Fig. 9 illustrates the valve assembly 90 according to another embodiment of the present invention.This embodiment is the improvement of embodiment shown in Fig. 5, and all components identical all use same label to provide.Two embodiments' difference is that assembly 90 has shoulder 94 among a punching member 92 and this embodiment and has that some are flexible.Thereby the core 96 of member 34 can be pressed to barrier film 42 slightly, and punching member 92 will be in hole of that barrier film upper punch then.This hole will seal when static, and will open when exerting pressure in the both sides of barrier film.
Be appreciated that punching member 92 can have one and make liquid through its chamber of flowing.Perhaps, liquid can be flowed through around the space 98 of punching member.
Figure 10 with reference to the accompanying drawings, Figure 10 illustrate a two-way valve, and it is totally represented with 100.This two-way valve is formed by two valves 102 and 104 structures, and in this specific embodiment, valve 102 is similar to the valve shown in above-mentioned Fig. 6 with 104.
First valve 102 is one-way valves, and a permission is flowed along the direction of arrow 106, and second valve 104 is that one permission is along the mobile one-way valve of the direction of arrow 108.The fluid output 110 of this second valve 104 is connected on the fluid input pipe 112 of first valve 102, and inlet duct 112 has a free end 114, and valve 104 comprises a fluid input 115.
Be arranged so that two-way valve 100 has three operating positions.At first operating position, make fluid flow into through free end 114 and inlet 116, and it is described as top embodiment about Fig. 6, when fluid pressure surpasses a certain threshold value, barrier film 118 distortion of first valve 102 make liquid flow out by one in this barrier film hole (not shown) that is pre-existing in and through outlet 106.
At second operating position, only allow fluid to flow into, and the barrier film 120 of second valve 104 is used as an one-way valve, thereby fluid can only flow out by the outlet 106 of first valve member 102 through free end 114.
When the fluid input 116 that only allows fluid to pass through second valve 104 flows into, the 3rd operating position occurs, thereby fluid only flows by free end 114, this is mainly owing to so that the desired high pressure of barrier film 118 distortion.
Yet one of valve assembly shown in Figure 10 concrete uses is for example in patient's feeding systems, wherein a tube feeding is connected in guiding patient's the outlet of first valve 102.The first liquid nutrition product container (not shown) is connected on the inlet 116 of second valve assembly 104 through a pump (known and also unshowned as itself).When first mode of operation, pump pumping liquid from second liquid-container enters inlet duct 112, thereby the liquid pressurized is not by first valve assembly 102 but by second valve assembly 104.When second mode of operation, pump is with opposite direction work, thereby with in first liquid-container the liquid of the amount of having counted suck and to lead in the pipeline of second liquid-container, pump reverse operating more then, thus as mentioned above by first valve assembly 102 will the described amount of having counted liquid pressurize.By this way, can will alternately be supplied to patient from the liquid of any container in two containers such as nutrient and water or rinsing agent.
What can also see in Figure 10 is bump 122 and the annular protrusion 126 that stretches out from the rear wall 124 of valve assembly, to be used for guaranteeing that respectively barrier film 118 and 120 is not fixed to the rear wall 124 of valve assembly 102 and 104, and guarantee not (just along direction) upward distortion in opposite direction of elastic diaphragm towards valve inlet, only flow so that guarantee fluid along a direction.
